Postgraduate Study

The Institute of Astronomy offers the opportunity to study for the PhD degree, which is normally completed in three years. The format is almost entirely research-based, and while projects may be exclusively theoretical or observational, many combine aspects of both. Many projects incorporate aspects of Data Science, including machine learning and artificial intelligence.

It is normal for students to attend several relevant international conferences during their three years of study, often presenting their own research work. Some students working on observational research projects undertake observing trips (s) to major international observatories.


Open Days

The University hosts and attends fairs and events throughout the year, in the UK and across the world. We also offer online events to help you explore your options:

  • Discover Cambridge: Master’s and PhD study webinars - these Spring events provide practical information about applying for postgraduate study.

  • Postgraduate Virtual Open Days - taking place in November each year, the Open Days focus on subject and course information.
